Well, I do agree, I would have gotten a PS3, since I was a huge Sony fanboy when I was little.
I got PSX and PS2, ah, good ol' Spyro, Crash Bandicoot and Jak and Daxter days. However, the one sole reason I got a 360 was just due to the fact that all my friends had it. I'd much rather play over Live with buddies from school than sit and play Single Player, or online with some random people. I love Sony, always been an amazing company, but I'm with the Xbox 360 just because I have that connection with friends.
